Claims.

This invention relates to a device for forming designs with yarn, suchas the iiower and pompon design shown and described hereinafter. Theprincipal object of the invention is to provide means for forming suchdesigns rapidly and with uniformity. It is also an object of theinvention to make it possible to change the size of the design quicklyand easily.

The nature and objects of the invention will best be understood from thefollowing disclosure in conjunction with the accompanying drawing, inwhich:

Fig. 1 is a side view in elevation of the tool of the invention;

Fig. 2 is a top plan view, partly broken away;

Fig. 3 is a similar view showing a different position of operating partsfrom that shown in Fig. 2; and

Fig. 4 is a top plan view of a typical product formed with the tool ofthe invention.

In the drawings, a hollow head I is provided with a recess 2 carrying aturnable disc 3 having holes 4 in which one end of a plurality of wirengers 5 are pivoted. The ngers 5, which are bent as shown, have straightprojecting ends 6 which are slidable in openings 'I in a disc or plate 8which is secured to the head I. The disc 3 is also secured by anysuitable means to a rod 9 enclosed within and coaxial with a tube I0,which serves as a handle. The outer end of rod 9 carries a knurled knobI I. Rotation of knob II and consequent rotation of rod 9 turns disc 3and thereby protrudes the ends of fingers 5 as shown in Fig. 2 or, byopposite rotation, retracts them as shown in Fig. 3.

The top of the tool and the head I are covered by a plate or cover I2secured as by screws I3, and diametrically opposed holes I4 are formedtherein which are adapted to receive the pins Iii-I5 projecting fromcrosshead I6 removably secured by said pins to said cover plate. Cross-'head I6 has a generally convex middle top portion II flanked byelevated shoulders I8. The convex portion is substantially throughoutits length provided with teeth I9. The lower middle portion of saidcrosshead is provided with a generally concave portion 28 flanked byslots 2 I--ZI which preferably begin as narrow channels 22 adjacent thecurved portion 2Q and widen into pearshaped extremities 23.

In operation, the ngers 5 are protruded, the crosshead is removed, andyarn is passed back and forth diametrically across the top plate andaround the ngers 5, each passage across being usually on the nextadjacent diagonally opposed ngers-ffrom the ones initially chosen-tostart with. The process is repeated, the fingers being utilizedprogressively around the head until at least one complete series ofloops is formed. If desired, this circuit may be repeated one or moretimes. Then a needle (not shown) is employed to gather the crossedmid-sections of yarn. Thereupon the crosshead is placed on the coverplate over the looped yarny and repeated windings, preferably of a,different colored yarn, are made transversely of the crosshead from thecentral concave part to the central convex part- The lower extremitiesof a wind are held bunched in the concave part, the middle portion ofthe yarn wind pass across the vertical face and back of the crosshead,and the upper end of the successive winds are held on the teeth I9 andbetween the shoulders I8. The shoulders prevent displacement of the yarnfrom the mid-section, while the teeth prevent relative displacement ofthe windings.k Thus the windings can be uniformly and accuratelycentered with respect to the central part of the loops of yarn held byiingers 5, and the mid-section of the upper winding can be built up.When suicient material for a top-knot or pompon has been wound, the endis secured with the help of a needle, which onat least some of itsstrokes will be passed through slots 2 I-ZI to encircle the lower partof the upper winding. vOther strokes will penetrate the mid-portionofthe looped lower winding. When the top-knot is secured, its upper partis cut along the sides of the toothed portion with scissors. Thecrosshead is then removed, and, except forA any desired final trimming,the pompon is'complete. gers 5, and the whole design removed. The edgesof the loops are secured or otherwise treated in a manner not involvingthe use of the tool of the invention.

In order to change the size of thepetals or loops of the design, thedistance travelled in forming each loop may be increased by placing aspacer (not shown) between the cover plate I2 yand. the base plate 8.

We claim:
